In this paper, we discuss the estimation of passivity based on input-output data without a system model. In the conventional data-driven estimation method based on the gradient approach, the convergence is slow and a large number of experiments is required. Therefore, we propose the method of reduction in the amount of data for data-driven passivity estimation to MIMO systems. Furthermore, we show the convergence property of the proposed method. In addition, through numerical simulations, the effectiveness of the proposed method is verified.

Judder is well known as a vibration that occurs in a dry clutch. In order to maintain the ride quality and quietness of dry clutches, research on judder analysis and mechanical design to suppress judder is actively pursued. This paper describes the design and implementation of robust control techniques as an approach to suppressing judder during gear shifting in traction-controlled transmissions. This paper is concerned with transmissions that exhibit strongly nonlinear frictional characteristics that can only be approximated by higher order polynomials. Specifically, the coefficient of friction varies significantly nonlinearly with the rotational speed during gear shifting. In this paper, the controller is designed by expressing this nonlinear property as the uncertainty of the frequency. Simulation and bench test results are presented to validate the validity of such an approach. The results show that judder-free shifting is possible with the proposed approach. Furthermore, the requirements of three controllers are presented by analyzing the robust controllers.

This paper proposes an approach for automatic controller tuning based on experimental data only. It determines the controller parameters for a given cost function without knowing the true plant dynamics via Bayesian optimization. The validity of the proposed method is tested through some numerical simulations. Then, the proposed method is applied to PID controller tuning for an actual motor positioning system. The experimental results show that the proposed method improves the control performance effectively.
